Volume scout from atlas

I opened a new protocol and did the mixed headmodel so I obtained the inversed current density unconstrained map. Then I make a new atlas volume scouts add the scouts to the atlas from aseg.mgz. So my issue now is that when I try to run either connectivity or Test I get this error. No matter how many scouts are there. I have tried with smaller and smaller numbers each time.
